In certain embodiments, the check valve part 76 of valve 70 is configured to open under the pressure in order to the fluid infusion of the nearside vestibule opening 26 by catheter adapter 14.Like this, check valve part 76 can automatically be opened during fluid infusion, and automatically closes when infusion stops.This ability can be eliminated the needs for valve actuator (this valve actuator is mechanically opened valve).
In certain embodiments, one or more gap 84 in valve 70 allows that guide needle (not shown) is through valve 70 and passing through, and the end portion 20 that makes thus the sharp distal tip of pin can surmount conduit 12 is distad extended.After conduit insertion process, pin is removed from conduit tube component 10, and disposed safely.
In certain embodiments, pin scribbles silicone or the class quasi-fluid of significant quantity, as fluorosilicone.The object of coating fluid has three.First, coating fluid plays the effect of the lubricant between the outer surface of pin and the abutment surface in gap 84.Thereby when pin is extracted out from valve 70, coating fluid prevents undesirably bonding between the outer surface of pin and the abutment surface in gap 84.The second, too much coating fluid accumulates in gap 84, helps thus seal valve 70, to prevent that blood flows back to through barrier film after removing pin.Along with pin is removed from conduit tube component 10, too much coating fluid accumulates in gap 84.Specifically, when pin is just extracted out through valve 70, the abutment surface in gap 84 plays the effect that coating fluid is wiped from the outer surface of pin, makes thus coating fluid move in gap 84.The 3rd, coating fluid plays the effect of lubricant, to prevent undesirably bonding between the apparent surface in gap 84.
Coating fluid can comprise any bio-compatible lubricant.In certain embodiments, coating fluid comprises lubricant, and as non-moistening lubricant, this non-moistening lubricant is applied on the interface between pin and gap 84, with may leaking of further eliminate fluid and/or air.Non-moistening lubricant may be also of value to prevent for gap tear or other damages, when pin being removed from conduit tube component after conduit inserts, may occur to tear or other damage for this of gap.Non-moistening lubricant also can promote suitably again the aiming at of apparent surface in gap 84 after the removing of pin.The non-limitative example of non-moistening lubricant comprises the non-wetted material of known PTFE base, as also used: from the Endura of Endura Coating Co.; A20, E-20,1000-S20, FEP Green, PTFE and X-40 from Tiodize; Cammie2000 from AE Yale; From 21845 of Ladd Research; MS122-22, MS122DF, MS-143DF, MS-122V, MS-122VM, MS143V, MS-136W, MS-145W, U0316A2, U0316B2, MS-123, MS-125, MS-322 and MS-324 from Miller-Stepheson; And from the 633T2 of Otto Bock.The non-moistening emollient type material of various non-PTFE bases comprises: from the Dylyn of ART; Nyebar, Diamonex, NiLAD, TIDLN, Kiss-Cote, titanium oxide; Fluocad Fluorochemical Coating FC-722 from 3M; Permacote from Dupont; From Plasma Tech, the Plasma Tech1633 of Inc.; And silicone spray.
Still with reference to Fig. 2, at catheter adapter 14, comprise that in those embodiment of port 50, valve 70 can play the effect of port valve.To understand, in further embodiments, catheter adapter 14 does not comprise port 50.As illustrated, the tube portion 78 of valve 70 can be positioned in the interior bore 60 of catheter adapter 14, makes the opening 52 of the outer surface 74 covering ports 50 of tube portion 78.While so locating, valve 70 can prevent the fluid outflow port 50 in vestibule 76.In addition, valve 70 can be configured in order to crumple at least in part when fluid being incorporated in port 50, thereby allows that fluid enters into the interior bore 60 of catheter adapter 14 by opening 54.
Valve 70 can be designed to, when by predetermined pressure inwardly crumple at least in part when the opening 52 of port 50 is applied to valve 70.Predetermined pressure generally can be less than and at fluid, during the infusion of port 50, by opening 54, press the amount of the power of valve 70.In each embodiment, the tube portion of valve 70 is flexibility or semiflexible.Valve 70 can be made by various flexibilities or half flexible material, and these materials comprise for example silicone, silicone rubber, polypropylene or other suitable material.The flexibility or rigidity of material can affect to be opened valve 70 and allows fluid to enter the predetermined pressure that catheter adapter 14 requires.More flexible material will require less predetermined pressure, and will require larger predetermined pressure compared with the material of rigidity.
As illustrated, the tubular form of the tube portion 78 of valve 70 is arranged to, and the passage in the valve body of valve 70 can be in crumple under predetermined pressure.Tubular form also can provide structural strength, and this structural strength is against the outer surface 62 of opening 52 maintaining valves 70 of port, until apply predetermined pressure.Can select the thickness of the wall of pipe type valve 70, to regulate the predetermined pressure of valve 70 being opened to requirement.Thereby, by increasing the thickness of the wall of tube portion 78, require larger pressure so that valve 70 is opened.By reducing wall thickness, require less pressure.In addition, the flexibility or rigidity based on forming the material of valve 70, can regulate wall thickness.For example, compared with rigid material, will allow thinner wall, these thinner walls make and can open port valve by the threshold force identical compared with heavy wall of making compared with flexible material.Correspondingly, with the flexibility of the combined valve 70 of the shape and size of valve 70, when predetermined pressure can be allowed to valve 70 crumples when opening 54 is applied on valve 70.
In each embodiment, valve 70 is placed in groove or passage 90, and this groove or passage 90 comprise the negative area of the inner surface of catheter adapter 14.The external diameter of valve 70 can be configured to generally in order to be placed in consistently and securely in groove or passage 90.For example, in certain embodiments, the external diameter of valve 70 is chosen to, has both been less than or has been approximately equal to the diameter of groove or passage 90, be a bit larger tham again the diameter of interior bore 60.Like this, valve 70 can remain in groove or passage 90 between the operating period of conduit tube component 10.In other structures, other features, as the nearside at valve 70 and the projection in distal end, are held in place valve 70 in order to help.
As shown in Figure 2, catheter adapter 14 and double-purpose valve 70 provide several useful features.For example, valve 70 do not require as desired in blood control valve in order to open the executor/actuator of valve.This can reduce the quantity of required element.This same characteristic can be so that catheter adapter 14 has the length reducing, and if it holds valve actuator/actuator, it will need certain length.In addition, because valve 70 is opened under the pressure from infusion line, and automatically close for the pressure from vein, so it is can be reusable.
As shown in Figure 3, in some constructions, the nearside vestibule opening 26 of catheter adapter 14 can seal with cap 100 during catheters irrigation process or other process.Cap 100 can optionally be connected with nearside vestibule opening 26, and seals this opening.For example, according to some medical treatment customs, as Europe medical treatment custom, during the initial flush of conduit tube component 10 or for infusion, cap 100 and nearside vestibule opening 26 are connected, to prevent that fluid from flowing out the proximal open 26 of catheter adapter 14.
As shown in Figure 4, as addressed during initial flush process or fluid infusion, the check valve part 76 of valve 70 can be by fluid 110 force opens, and this can allow fluid 110 through the vestibule 60 of catheter adapter 14, to pass through from fluid source 112 along distal direction.Meanwhile, valve 70 can prevent that fluid from passing port 50 and escaping.When removing fluid source 112, valve 70 can be in the situation that do not have the power of fluid to cut out.When closing, check valve part 76 can stop fluid and/or blood proximad by the leakage of valve 70.In addition, as illustrated, during such fluid infusion, the tube portion 78 of valve 70 can keep against the opening 52 of port 50, to prevent that infused fluid 110 from leaving through this opening 52.
As shown in Figure 5, during initial flush process or for through the infusion of port 50, fluid 110 can flow to nearside vestibule chamber 64 from port 50.Along with fluid enters nearside vestibule chamber 64, the pressure in this chamber increases, and valve 70 is opened.Along with valve 70 is opened, fluid 110 can flow in distally vestibule chamber 62, and continues to flow to patient.
As illustrated, valve 70 and/or catheter adapter 14 can be configured to force fluid 110 to arrive the nearside sidepiece of valve 70 rather than arrive the distally sidepiece of valve 70 or arrive two sidepieces simultaneously.Correspondingly, the distal end of valve 70 can form sealing with the inner surface of catheter adapter 14.For example, the exterior section of the distally sidepiece of valve 70 can be bonding with the inner surface of catheter adapter 14, with the distal end around valve 70, forms sealing.In another example, the exterior section of the distally sidepiece of valve 70 can have than the large external diameter of the part of the valve 70 at this end nearside or other external dimensions.Similarly, the inside dimension around the catheter adapter 14 of the distally of valve 70 sidepiece can have the little internal diameter of part than the catheter adapter 14 at this region nearside.These examples can form sealing more closely between the distal end of valve 70 and catheter adapter 14, and this impels fluid to flow in nearside vestibule chamber 64.In another example, the exterior section of the nearside sidepiece of valve 70 can have than the little external diameter of the part of the valve 70 in this distally, end or other external dimensions.Similarly, the inside dimension around the catheter adapter 14 of the nearside sidepiece of valve 70 can have the large internal diameter of part than the catheter adapter 14 in this distally, region.These examples form weak sealing between the proximal end of valve 70 and catheter adapter 14, and this impels fluid to flow in nearside vestibule chamber 64.
As shown in Figure 6, in certain embodiments, catheter adapter 14 comprises valve actuator 140.Valve actuator 140 can be provided in the mechanism in catheter adapter 14, and this mechanism has proximal contact surface 144, and this proximal contact surface 144 is contacted by vascular access equipment, and this vascular access equipment is inserted in the opening 26 of catheter adapter 14.Vascular access equipment can press against on contact surface 144, so that distad advance in the gap 84 that valve actuator 140 passes valve 70 (shown in Figure 9).Along with it distad travels forward, the detecting head surface 142 of valve actuator 140 presses against on the flap 80,82 of check valve part 76, to open gap 84.Valve actuator 140 can comprise probe segment 146, and this probe segment 146 can have cross section, and the shape and size of this cross section are set for it can be inserted through the gap 84 of valve 70.In addition, valve actuator 140 can have various features, structure and structure, and movable and remain in catheter adapter 14, as described at U.S. Patent Application Publication text No.2011/0046570, the open text of this application was submitted on August 20th, 2009, title is " being used to provide the system and method for flushable conduit tube component ", and the open text of this application is by reference to being all included in this.
As shown in FIG. 7 and 8, in having the embodiment of valve actuator 140, can provide cap 100, this cap 100 has butt sun Rule parts 150.In some constructions, cap 100 can comprise butt sun Rule parts 150, and the curtailment of these butt sun Rule parts 150 is so that before valve actuator 140 and then valve 70 is opened.For example, the positive Luer collar 152 of cap can be extended far than the butt sun Rule parts 150 in this axle collar 152.As shown in Figure 8, when the proximal end 22 of cap 100 and catheter adapter 14 is connected, the fluid 110 of entry port 50 can rinse the nearside vestibule chamber 64 around valve actuator 140, and subsequently by valve 70.
As shown in Figure 9, in the time of in the nearside vestibule opening 26 that segregation apparatus 112 is inserted into catheter adapter 14, valve actuator 140 can distad advance through the gap 84 of valve 70, and valve 70 is opened.In such a way, when catheter adapter 14 is connected with segregation apparatus 112, when being connected with IV infusion device, valve 70 can be opened.
